GPS Tracklog: TomTom has quietly been updating the firmware of older units, adding their new Map Share and Help Me features. Newly supported units include the TomTom GO 300, 510, 700, and 910, along with the TomTom ONE and ONE XL. To upgrade, simply connect your device to TomTom HOME. The only catch is that, for most models, you’ll need to have a map version of 6.75 or higher.
“TomTom Map Share™ is a unique map improvement technology that enables users to easily and instantly improve maps directly on their device. Via TomTom HOME, TomTom’s free desktop software application, Map Share™ users can also receive map improvements made by the TomTom community so that they always have the most-up-to-date maps available.”
